ADVERTISING MAGHINE. l

Be-it known that I, ISAIAH W. SrLvnsTnn,'of the city, county, and State of New York, have invented a new and useful machine for advertising at hotels and other public places, called by mean Advertising Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makinga part of. this specification,

in which- Figure 1 is a perspective view of the machine,'as seen in actual operation. Figure 2 is a perspective view ofi the muchinepy, the glass door or front being removed.

Figure 3 is a transverse secti n, showing the machinery which communicates motion to the rollers B and C and the curtain A; and

Figure 4 is a transverse section of a. portion of the works at the opposite end of the roller B, designed to check or retard the motion of the rollers B and Cl.

A is a curtain of paper upon which have been printed a number of business cards or advertisements. B

and C arewoodenrollers carrying a, narrow belt over their centres, to which belt is attached the endless curtain A. D is an ordinary clock-spring attached to the shaft and wheelE, to which are geared the pinion and wheel F, to which are geared the pinion and shaft G. The shaft G connects 'with the e e-litre ofthe roller Bi Upon winding up the spring D motion is communicated to the rollers B and C and the curtain A. H is an ordinary eight-day marine-movement clock with thestrike part removed in order to make room for the following wheels 1 and shafts: shaft 2', which has a single tooth or arm, g, notching or gearing into the hour-wheel K of the clock at eaehrevclution, and also-the wheeltL, gearing intothe pinion M,'which is placed on a shaft attached to the centre of the'roller B. N is a glass door placed over the whole.

In the construction of this machine, the objects sought to be accomplished were, first, the quick revolution of the curtain A at given intervals of say from one to five minutes each; and second, the running oft-he whole machine for a length of time, so as not to 'requirettoo frequent winding up. the quick motion of the curtain it was thought the eye of a stranger would be attracted, as anything in motion naturally attracts attention,

while the interval of rest, or apparent rest, would facilitate the reading of the advertisements 31 the revolution of the curtain would also permit the whole of itto headvantageously employed; To obtain thescends I con struct, my machine as follows: To communicate 'moticn of the necessary .duration of time I use springs, (from one to three springs similai to those used in ordiuarj' eight-day marine-movement clocks, are sufiicieut for an ordinary muchine,) whose power, either singly or combined, is made to operate on a succession of large and small wheels, as. illustrated 'by' E, F, and G,fig. 3, and finally on the roller B. The number of revolutions of the roller B, together with-the time required for the tooth J top-ass throughthe periphery of the hour-wheel of the clock,toge thcrwith the time the clock will run, determines the length of time the whole machine willoperate. Increasing the number. of revolutions of the roller B decreases the power with which it turns, providing the spring remains of the same force; to increase, therefore, the number of its revolutions, greater spring power must be used. Having obtained the requisite'spring force toz'uovc the rollers 13 and C, with the ourtainattnched,

a sufiicient number of revolutions, I attach the centre of the opposite end of roller 13 to the shaft on which is wheel M, fig. 4, revolving within the framework of theclock H, and geared into wheel L, also revolving within the framework of the clock. The proportionate number of notches in wheels L and 'M determines the number of revolutions the roller B will make at each revolution of the tooth J. The distance the curtain travels at each quick movement is determined by the diameter of the roller .13 and the number of its revolutions. On the some shaftwith the wheel L I place the tooth or arm 5, so that at each revolution it strikes into the teeth of the hour-wheeler" the clock, by which wheel its motion is checked or retarded untilit passes through and comes out on the opposite side, when it is relieved and againfiies around, to again pass through as before, thep-eriphery vof the hour-wheel, and so on continunlly'until the spring I) is exhausted. While the tooth J is passing through the periphery of the clock-wheel the motion of the curtain A; is so slow as to be imperceptible. By placing a wheel with fewer teeth or: its periphery on the same shaft with the houro'rhcel of the clock, and causing the tooth J topuss through it instead of the hour-wheel, I obtain a more frequent rapid movement of the curtain,. I place the entire machinery in a box of any desired lcrigth'and width, and of a depth just surhdient to enclose it. I make the rollers 13 and G to extend the entire width of the buX, less the space occupied by the moveherein described and set forth.

ments, cutting circular holes through the box on either side, for the purpose of winding up the springs. The curtain I make to extend the entire length of the box, revolving over the rollers at each end, and of the width of the rollers, the object-being tosecure as large a space as possible for advertisements. Roller-B, with the machinery at either end, may be at the top while roller 0 is at the bottom, or the position may be reversed, and roller B be placed at the bottom, with roller 0 at thetop of the case, as they be desired or most convenient for winding up the springs; The centre of the rollers B and O I make a trifle larger, as in ordinary pulleys, and run over themn narrow belt of cloth one to two inches wide, and to this belt I attach the paper curtain A, on

which advertisements have previousl been printed. When all is completed and placed in the box or case, the. front is closed by the door N, which is made partly of glass and partly of wood, so as to conceal the machinery .end show only-the curtain A with the advertisements, It can then be placed in any conspicuous position.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The application to advertising of an endless curteinmade to revolve automoltically at given intervals, quickly, so as to attract attentionby its motion, and then slowly, so as to he apparently motionless, and to allow of the eusj reading of the advertisements.

2. The device whereby the power moving the curtain is retarded at regular intervals by means of the arm J notching into, passing through, and being relieved from the periphery of the clock-wheel, substantially as ISAIAH W. SYLVESTER.
